Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a variable prize winning device for a pachinko machine that rotates a movable member by driving an electromagnetic solenoid to change the acceptance state of a batted ball.

<Prior Art> In pachinko machines, there are many known variable winning devices in which a movable member changes the state in which it receives a ball by operating an electric drive source. In particular, a device in which a movable member is rotated by combining an electric drive source such as an electromagnetic mechanism with a rack and pinion gear is known, for example, from Japanese Utility Model Application Publication No. 55-56483. In this type, the rotating pin of the movable member is directly connected to the shaft of the pinion gear, and the operation of the electromagnetic mechanism is directly transmitted to the rotating pin.

<Problems to be Solved by the Invention> However, the conventional variable prize winning device which has a rotary structure of a movable member that combines an electric drive source and a rack and pinion gear does not have the rotary pin of the movable member attached to the axis of the pinion gear. Since the directly connected fulcrum and the point of action are the same, as the movable member repeats rotational movement, a relatively large load is continuously applied to the connection between the base of the movable member and the rotation pin, resulting in long-term damage. If used for a long time, the joints may crack and break. In addition, at the beginning of the rotation of the movable member, which requires quick and repeated rotation, a large torque is required on the electric drive source side, and when the movable member stops rotating, centrifugal force is applied to the tip of the movable member. As a result, torsional stress concentration occurs in the above-mentioned connecting portion. For this reason, the electric drive source becomes large and the entire variable prize winning device has a large structure, and the connection between the base of the movable member and the rotation pin is given a special structure to strengthen it, which increases costs. It had some drawbacks.

<Means for Solving the Problems> The present invention has been proposed in view of the above-mentioned problems.Introduction holes are provided in a mounting plate that is attached to a game board, and a pair of opposing movable members are provided on the surface of the mounting plate. A box-shaped pocket frame is provided from the front so as to cover the shaft supports of both movable members and communicate with the introduction hole. A drive mechanism is disposed in which the pinion gears are rotatably engaged with each other, and both movable members and both pinion gears are interlockably connected to each other by a drive member extending through the mounting plate. and an electromagnetic solenoid are connected by an operating member, and the reciprocating motion of the electromagnetic solenoid is transmitted to a drive mechanism, and the drive mechanism converts this reciprocating motion into a rotational motion and transmits it to both movable members, so that both movable members The ball is rotated to change the receiving state of the ball.

<Operation> The reciprocating motion of the electromagnetic solenoid is converted into a rotational motion by a drive mechanism having a pinion gear that easily meshes with the electromagnetic solenoid, and the rotational motion by the pinion gear is transferred to the surface of the mounting plate by a drive member extending through the mounting plate. By transmitting the information to a rotatably supported movable member, it is possible to change the state in which the movable member accepts a batted ball.

<Example> An example of the present invention will be described below based on the drawings.

The variable prize winning device 1 according to the present invention has a mounting plate 2 that is attached to the surface of the game board, and an introduction hole 3 is provided in the lower part of the mounting plate 2. Fixed shafts 4R and 4L are installed in the left and right upper portions of this introduction hole 3, and the fixed shafts 4
A pair of opposing movable members 5 are provided at the tips of R and 4L.
Rotatably support R and 5L. Further, a box-shaped pocket frame 7 is provided so as to cover the shaft supports 6 of the movable members 5R, 5L from the front, and the pocket frame 7 is communicated with the introduction hole 3. Thus, the movable members 5R, 5
A batted ball that enters between L is guided by movable members 5R and 5L, passes through introduction hole 3, and is led out to the back side of mounting plate 2.

A drive mechanism 8 is provided on the back surface of the mounting plate 2. This drive mechanism 8 extends to the back side of the mounting plate 2 by passing drive members 9R and 9L, which are set up on the back side of the movable members 5R and 5L, through long holes 10R and 10L formed in the mounting plate 2, respectively. and the driving members 9R, 9L.
are loosely engaged with the engagement holes 13R, 13L of the pinion gears 12R, 12L rotatably mounted on the rear end portion 11 of the fixed shafts 4R, 4L, respectively, and the pinion gears 12R, 12L are moved up and down on both sides of the rack 14. It meshes with the. That is, pinion gear 12R,
12L engages with the right and left sides of the rack 14, and the operating member 15 provided at the upper end of the rack 14 so as to extend rearward is guided by the guide groove 17 of the holding plate 16 so that it can move up and down. At this time, by rotating the right and left pinion gears 12R, 12L diagonally with each other, the movable members 5R, 5L are rotated diagonally with each other via the drive mechanisms 9R, 9L.

Further, a dividing groove 18 is provided at the rear end of the operating member 15.
A disc 21 attached to the tip of an operating rod 20 of an electromagnetic solenoid 19 is slidably engaged with this groove 18. Therefore, when the electromagnetic solenoid 19 is energized, the operating rod 20 protrudes upward, causing the rack 14 to rise and engage the pinion gear 12.
By rotating R and 12L, the driving members 9R and 9L perform an arcuate movement, and the movable members 5R and 5L are opened to the open state shown by the chain line in FIG. 2 (state X2). On the other hand, when the electromagnetic solenoid 19 is demagnetized, the operating rod 20 is retracted by the spring 22, and the movable members 5R and 5L are closed to the closed state shown by the solid line in FIG. 2 (state X1).

However, in this closed state, the movable members 5R, 5
A spacing slightly wider than the diameter of the game ball is maintained between the L's, thereby making it possible for the batted ball to win a prize with a low winning rate. On the other hand, in the open state, the movable members 5R and 5L fully open left and right, resulting in a much higher winning rate.

According to the modulation winning device 1 configured as described above,
The reciprocating motion of the electromagnetic solenoid 19 is converted into a rotational motion by the drive mechanism 8 and transmitted to the movable members 5R, 5L, thereby changing the ball receiving state of the movable members 5R, 5L. 5
L can be reliably converted with a small turning force, and the conversion states of the movable members 5R and 5L can be quickly controlled by excitation or demagnetization of the electromagnetic solenoid 19. Therefore, according to the present invention, the winning states of the movable members 5R and 5L can be efficiently and smoothly changed by controlling the electromagnetic solenoid 19.

FIG. 4 is a front view of a pachinko machine 23 in which a plurality of variable winning devices 1 according to the present invention are arranged, and a special winning device 26 is located in the center of a gaming section 25 surrounded by a guide rail 24 of this pachinko machine 23. Variable winning devices 1A to 1H are arranged radially around the special winning device 26, and specific winning holes 27R and 27L are provided on the upper left and right sides of the gaming section 25.

Then, the electromagnetic solenoid 19 of each variable prize winning device 1A to 1H is controlled by the electric control device 28,
For example, when a batted ball wins a prize in the specific winning openings 27R, 27L, each variable winning device 1A to 1H is sequentially opened clockwise based on the detection signal,
When a ball hits the special winning opening 26' of the special winning device 26, each of the variable winning devices 1A to 1H are simultaneously opened based on the detection signal, or a variable winning device installed at the top of the gaming section 25 is operated. Device 1
The first group of A, 1B, 1H and the second group of variable winning devices 1C, 1D, 1E, 1F, 1G arranged at the bottom may be opened alternately and simultaneously, or the variable winning devices 1A to 1H may be opened alternately and simultaneously.
The conversion mode of 1H can be set as appropriate.

If a plurality of variable winning devices 1A to 1H as described above are arranged in the pachinko machine 23, and the conversion mode of the variable winning devices 1A to 1H provided in the gaming section 25 is set to be different depending on the winning mode of the batted ball, This makes pachinko a highly varied and interesting game. In addition, in the closed state of the movable members 5R, 5L in the embodiment, a gap slightly wider than the diameter of the game ball is maintained, but in addition to this, the movable members 5R, 5L may be in a completely closed state.

<Effects of the Invention> In summary, according to the present invention, the reciprocating motion of an electromagnetic solenoid is converted into a rotational motion by a drive mechanism having a pinion gear that easily meshes with it, and the rotational motion by this pinion gear is transmitted through a mounting plate. A driving member extending in the direction of the ball is transmitted to the movable member, and the driving member rotates the movable member to change the receiving state of a batted ball. Therefore, it is possible to rotate the movable member with a smaller force than in the conventional system, and by using a small electromagnetic solenoid, the entire variable prize winning device can be formed into a compact single component. In addition, the fixed shaft of the movable member has a structure that does not transmit the operation of the electromagnetic solenoid, so the shaft support can be simplified, and
Even if the movable member is operated quickly and used for a long period of time, its fixed shaft will not be twisted or damaged. Furthermore, since a large centrifugal force does not act on the tip of the movable member when the movable member rotates, the rotational movement of the movable member can be made faster and more stable, and various changes in the receiving state of the ball can be made. Become.
